The present invention relates to improven boiling point of approximately 500o F. and ments in the manufacture of gasoline from showing about 50% otlat 3740 F. natural gas and other gases containing gaso- After the superheated steamv has been adline constituents in'vapor form.

A steaml suitable for carrying out the-"invention is distillation of the stock is thereby producedy diagrammatically illustrated. and its lighter constituents are driven off .0 Referring more particularly toi-the draw'- through pipe 16.
